All of the previous methods and recipes work quite well, but we like to emulate the "shore-side" method used when we catch several nice sized rainbow's here in the western U.S. At home, I heat an appropriate sized cast iron skillet over medium heat with a healthy dose of olive oil (EVO, of course) covering the bottom of the skillet. The trout are sprinkled with a pinch of Kosher salt, a good pinch of coarse ground black pepper (on the inside) and perhaps a shake of parsley leaves. The frying time for a 3/4 pound trout is about 3 to 5 minutes per side. It becomes nice and crispy on the skin side, but the meat remains lightly pink and flaky. We remove the heads, simply to save room in the skillet. A friend does the same thing, but dredges the seasoned fish in a little flour to further enhance the crispiness... (works equally well on Brown, Brook and Cutthroat trout...)
